Don't bother with HP.com.au you won't find this information on there.
If you ever need to reset/re-calibrate the touchscreen on a HP 9000 9050 9040 etc printer try this.
- Turn off the printer.
- Hold down # and C buttons while turning the printer ON.
- A screen will shortly appear in the upper left region that has tiny black dot on it. tap this dot with pen or something pointy (although not as sharp as a knife as you'll damage the touchscreen). It won't really give you any feedback that you've pressed it.
- A second dot will appear in the lower right region of the screen. tap this dot.
- The printer will then boot as per normal and the touchscreen will be calibrated.
Result = Happy User :)
